I would like to stress that numbers such as those you are reporting are
MEANINGLESS if they are not expressed together with a statistical error.
I don 't know if an answer to your question exists, but without errors,
all discussion is impossible.

No, you cannot. The first line seems to request a proton fluence in region
TARGET (actually a proton total tracklength). But the second line needs a &
in the SDUM field in order to be considered a continuation card.
Read the Manual, command USRBIN:
WHAT(2) : particle (or particle family) type to be scored
...............................................
follows a list of generalised particles, which does not apply here
...............................................
Any other particle (or family of particles) requested will score:
a) if WHAT(1) < 10, ............ [not relevant here]
b) if WHAT(1) >= 10, fluence of particles (or family of
particles) with particle code (or name) = WHAT(2).
You cannot use USRBIN to score a particular residual nucleus.
